| 摘 要： | 提出一种基于功率协调的交直流并联系统可靠性评估方法。在求得交流、直流线路的最大输送功率后，对交直流系统功率进行合理的协调，得到整个系统输送功率满足负荷要求的概率性指标，用Monte Carlo模拟法对可靠性指标进行统计计算。文中同时给出进行交直流并联系统可靠性评估的算法，通过交直流并联系统的仿真计算，证明所提方法和算法的有效性。

| Abstract: | A novel reliability-evaluation method is presented based on AC-DC hybrid transmission systems in this paper. Under the constraintsof the system variables, the maximum transmission powers of AC and DC transmission lines can be carried out, respectively. Moreover, bythe reasonable regulation for the power of the AC system, the transmission power of the whole system is satisfied with the probability index ofthe requirement from the loads. Then, the reliability indices of the system are calculated statistically by the method of Monte Carlo. Mean-while, a reliability-evaluation algorithm for AC-DC transmission system is presented. It is manifested that the method and the algorithm arevalid through the simulation for a hypothetic AC-DC transmission system. |
